    Safety Instructions These safety instructions are intended to prevent hazardous situations and/or equipment damage. These instructions indicate the level of potential hazard with the labels of “Caution,” “Warning” or “Danger.” They are all important notes for safety and must be followed in addition to International Standards (ISO/IEC) , and other safety regulations.
  • Page 4 Safety Instructions Caution We develop, design, and manufacture our products to be used for automatic control equipment, and provide them for peaceful use in manufacturing industries. Use in non-manufacturing industries is not covered. Products we manufacture and sell cannot be used for the purpose of transactions or certification specified in the Measurement Act.
  • Page 5 Design / Selection Warning 1. Confirm the specifications. Products represented in this catalog are designed only for use in compressed air systems. Do not operate at pressures or temperatures, etc., beyond the range of specifications, as this can cause damage or malfunction. (Refer to the specifications.) We do not guarantee against any damage if the product is used outside of the specification range.

  • Page 12 Auto Switches Precautions Design / Selection Warning 1. Confirm the specifications. If the product is used with excess load applied or beyond the specification range, this may cause the product to break or malfunction. We do not guarantee against any damage if the product is used outside of the specification range.
  • Page 13 4. Take precautions when multiple rotary actuator are used close together. When multiple auto switch rotary actuator are used in close proximity, magnetic field interference may cause the auto switches to malfunction. Maintain a minimum separation of 40mm between rotary actuator.
  • Page 14 Mounting / Adjustment Caution 1. Do not drop or bump. Do not drop, bump or apply excessive impacts (300m/s or more for reed auto switches and 1000m/s more for solid state auto switches) while handling. Although the body of the auto switch may not be damaged, the inside of the auto switch could be damaged and cause malfunction.
  • Page 15 beforehand and make sure to connect the terminal with a built-in load (IN, etc.) to the 0 V terminal. (Do not connect the power supply terminal and the ground terminal directly when in a non-load state.) 5. Do not allow short-circuit of loads. <Reed>...
  • Page 16 5. Do not use in an environment where there is excessive impact shock. <Reed> When excessive impact (300m/s or more) is applied to a reed auto switch during operation, the contacts will malfunction and generate or cut off a signal momentarily (1ms or less). If further excessive impact is applied, the reed auto switch may break.
  • Page 17 Maintenance Warning Removal of equipment, and supply/exhaust of compressed air. Before any machinery or equipment is removed, first ensure that the appropriate measures are in place to prevent workpieces from dropping, run-away equipment, etc. Then, cut off the electric power and reduce the pressure in the system to zero.

  • Page 28: Setting Of Rotation Time

    5. Setting of Rotation Time Even if the torque - required by the load in the rotation movement is small, the shaft and/or internal parts could become damaged depending on the inertia of the load. Therefore, select an appropriate model for your application by taking the load’s moment of inertia, kinetic energy, and rotation time into consideration.
  • Page 29 (3) Moment of inertia of each style can be found with the calculation formula shown below. How to read Graph 1 Example 1. When CRB220 is used under conditions of moment of inertia of a load of 3.5x10-⁵kgm and rotation time of 0.12 seconds to move 90 degrees; Since the intersection of 3.5 x 10-5kgm on the vertical axis and 0.12 seconds on the horizontal axis is below the energy curve, CRB220 can be used.

  • Page 31: External Stopper

    External stopper If the kinetic energy - generated by the load exceeds the actuator’s threshold value, an external dampening function must be provided to absorb the energy. The figure below shows the correct installation of external stopper.  As a rotary actuator itself has a slight angular error due to the construction, use an external stopper when accurate positioning is required.
